17 Claims.

This invention relates to phonographs, and has especial utility in connection With phonographs of the type by which there may be recorded, or selectively recorded and reproduced, sounds such as dictation and the like.

For Well understood reasons such phonographs are usually arranged so that the translating device which cooperates with the record may be selectively placed in and taken out of condition for recordation on the record; a typical purpose of its removal from recordation condition may be its re-conditioning for reproduction of previously recorded matter. When it is desired to restore the translating device to recordation condition it is important that this be done at the proper position relative to the record, so that there may be avoided on the one hand an unnecessary wastage of record space, and on the other hand a re-recordation on parts of the record already recorded upon.

It is an object of my invention to provide novel and improved means for insuring the placement of the translating device into recordation condition at proper position relative to the record.

It is an object to provide improved means for controlling the return of the translating device to recordation condition with respect to any record in accordance with its prior conditionings relative to that record.

It is an object to provide improved means for insuring the initial placement of the translating device into recordation condition at the intended initial extremity of recording space on the record.

It is an object to for making permanent tions occupied by the it is reconditioned.

It is an object to provide a combination of registration-making and registration-scanning means for fulfilling broader objects of my invention.

It is an object to provide a control system wherein distinct registrations are made of positions at which the translating device is respectively placed in and taken out of recordation condition, and wherein those two types of registrations are jointly utilized in advantageous functional relationship to each other.

It is a general object to provide an improved phonograph of the type described.

Other and allied objects will more fully appear from the following description and the appended claims.

The phonograph in which my invention has been embodied may be generally described with reference first to Figures 1, 2 and 5. It includes a cast base plate I which is generally horizontal, but which may be provided with a curved step Ia. to bring its rear portion to a higher level than its forward portion, as may be seen in Figure 5. The base plate may be provided with a downward flange Ib along at least its front and rear edges, and along its rear edge may be hinged to a lower enclosure 2, the front of the base plate normally resting on a bracket 2a extending inwardly from the front of that enclosure. Extending upwardly from the base plate are the lefthand and righthand standards 5 and 6, respectively, and the intermediate standard 1, these standards serving to support various elements of the phonograph as hereinafter appears.

J ournalled in the standard 1 is a mandrel shaft 9 on which, to the right of that standard, is carried a record support in the form of a generally cylindrical mandrel ID'. This may for example be of the form disclosed in U. S. Patent No. 2,010,717, issued August 6, 1935, on application of H. F. M. Gramann, and its detailed description herein is unnecessary. It may be noted, however, that it includes a righthand end knob l5 over which a record may be slid leftwardly in mounting of the record on the mandrel, and which when pressed leftwardly when a record is on the mandrel will cause the rightward ejection of the record. Figures 1 and 5 illustrate a cylindrical record C, purely typically of a wax composition, mounted on the mandrel.

The mandrel shaft 9 extends to the left of standard 1 toward a driving pulley I1 rotatably mounted at the right of standard 5, the pulley I1 being rotated as by a belt and motor not herein necessary to show. Secured to the pulley I1, and splined on the end portion of the shaft 9, are the respective elements I8 and I9 of a clutch 20. The element I9 is provided with an annular groove I9', in which there is positioned a pin 2i secured in the upper extremity of a clutch-operating arm 22. The arm position is controlled by a start-and-stop device, not herein necessary to show, to shift the element I9 selectively into and out of engagement with the element I3, and so to engage and disengage the clutch to cause and stop rotation of the mandrel by the pulley I1.

Above and behind the mandrel there extend, between the standards 5 and 5, the respective carriage rods 23 and 24, along which there is slidable a carriage 49. The carriage extends forwardly over the mandrel, and carries in its forward portion a translating device 30 arranged, in manner hereinafter more detailedly apparent, forcooperation with the record C on the mandrel. The carriage may be driven rightwardly along the rods 23 and 24 by a feed screw 25, journalled between standards 5 and I behind the rod 23, and engageable by a feed nut 21 carried in the carriage. The feed screw 25 may be rotated, by a train of gears 2G coupling it rotationally with the mandrel shaft 9, coincidentally with mandrel rotation.

It will be understood that the mandrel II] and the carriage 4D form a system for producing translation-effecting relative movement between the record C and the translating device 39--e. g., a movement which causes either of the translating device styli (hereinafter mentioned) to traverse a spiral path on the record, for the translation of oscillatory energy into a recording on the record or vice versa. And while the described translation-effecting movement is the movement appropriate to the type of record and type of phonograph which I have chosen for illustrative purposes, 1 intend no unnecessary limitation of the broader aspects of the invention to those types or to the particular nature of that movement.

While the translating device 39 may in recordation be actuated by, and may in reproduction produce, oscillatory energy of any of a wide variety of natures, I have shown it as provided with an upwardly extending neck 29, to which a sound-conveying tube (not shown) may be attached for the conveyance of sound to and from the translating device. The translating device which has been chosen for illustrative purposes is a sound box, which in its most essential elements may for example be similar to that disclosed in U. S. Patent No. 1,989,198, issued January 29, 1935, on application of Charles Heunlich. While reference may lbe had to that patent for a more detailed disclosure of such a sound box, a general showing is present in Figure 6 of the accompanying drawings, to which the following sound box description is pertinent.

The illustrated sound box includes two generally circular members pivoted (as at point P) at the front of the device and extending generally rearwardly, the upper of these members being designated as 3l and the lower as 32. When both members are free of upward restraint, a smooth ball 34 attached to member 32 contacts the record surface, without effect on the latter, and a recording stylus 35 carried by the upper member 3| also contacts the record surface; the translating device is then conditioned for recordation on the record-e. g., for the engraving in the record surface of a groove of depth undulating in accordance with sound energy supplied to the device through the neck 29. When the upper member 3I only is held upwardly (as by means hereinafter described) both the ball St and the recording stylus 35 are held away from the record, and a reproducing stylus 3B, suitably carried by the member 32, is brought into contact with the record surface; the translating device is then conditioned for reproduction from the record-e. g., for the emission through the neck 29 of sound energy translated by the device from an undulating record groove being traversed by the reproducing stylus 3S. When both members 3l and 32 are held upwardly (as by means hereinafter described) the ball 34 and both the styli 35 and 36 are held away from the record; the translating device is then in neutral condition (which is that illustrated in Figure 6).

The carriage El is provided with a horizontal sleeve 43 secured between the lefthand and righthand side members of the carriage (4I and 42 respectively) and extending for a distance leftwardly from 4I, this sleeve slidably surrounding the rod 23 and forming a long bearing for the carriage on that rod. The means for variously positioning the circular members 3| and 32, and thus for selectively conditioning the translating device, comprises a member 6I) rotatably surrounding this sleeve 53 within the carriage; two arms 45 and 4B carried in the carriage and extending forwardly to underneath respective lugs 3T and 38 which respectively extend rearwardly from the circular members 3l and 32; and a mechanism for moving the arms 45 and 46, and therethrough the circular members 3l and 32, in accordance with angular movements of the member 60 about the sleeve 43, this mechanism being seen principally in Figure 6.

Between the carriage side members 4l and 42, behind the sleeve 43, is secured a cross rod 44. On this rod, just inside 4I and 42, are pivotally secured two respective ears 4l and 48 which extend forwardly from and support a generally vertical plate 49 hereinafter mentioned. Rotatably surrounding the rod 44 between the ears 4l and 48 are a series of three collars 5l, 55, 52 (seen in dotted illustration in the rear-view Figure 7) the arm 45 is secured to the righthand side of the lefthand collar 5l, while the arm 46 is secured to the lefthand side of the righthand collar 52, so that the arms are supported by and may be rocked about the rod 44. The principal portion of each of the arms 45 and 46 extends downwardly and forwardly from rod 44; but each arm also extends a short distance upwardly from rod 44, to have its top extremity engaged by the forward extremity of a respective tension spring, shown as 54 for the arm 46. The rear extremities of these springs are secured to a stationary cross rod 55 (at the rear of the carriage) to bias upwardly the forward extremities of the arms 45 and 45; this arm bias of course tends to cause the raising of both the circular members 3l and 32, and hence tends to establish a neutral condition of the translating device 3i).

The member 50, surrounding the sleeve 43 within the carriage, is generally cylindrically shaped; but some material is removed from its bottom, and two ears 6I and 62 extend generally downwardly from its respective extremities (as seen in Figure ll). Between these ears there extends a thin cross pin 59, on which three rollers (5l, 56, 58) are carried (also as seen in Figure 1l) When the member Fili occupies the angular position about sleeve 43 in which it has been illustrated in Figure 6, the horizontally aligned rollers 51 and 58 will respectively be in contact with top surface portions of the two arms 45 and 45, that portion for the arm 46 having been designated as 45". 'I'ne configurations of the top surfaces of the two arms are such that the forward arm extremities are then in raised position, and the translating device 35 is therefore in neutral condition.

From the portions typified by 45", toward the pivoting rod .44, the too surfaces of the arms 45 and 45 extend (similarly to each other, and as indicated by the arm in Figure 6) more nearly vertically than the rearward arcuate path traversed by the rollers upon rocking counterclockwise (when viewed as in Figure 6) of the mem- 45. Accordingly upon. such rocking (for example to bring the rollers into slight indentations indicated as 4S for arm 45) the arms will be rocked about rod 44 to bring their forward extremities downwardly; this results in a lowering of both the circular members Si and 232 and therefore conditions the translating device 3l! for recordation.

From the portions typified by 4E" the top arm surfaces extend forwardly with different elevational congurations. That of arm 45 extends a distance forwardly (for example to the slight indentation 45) approximately along the forward arcuate path traversed by the rollers 5l and 53 upon the rocking clockwise (when viewed as in Figure 6) of the member 6G. On the other hand, that of arm 45 extends (for example to the slight indentation 45W) materially more upwardly than that forward arcuate path. Accordingly upon such rocking (for example to bring the rollers into the indentations 45 and 46 the arm 45 will be left approximately in its Figure 6 position, while the arm 46 will be rocked to move its forward extremity downwardly; this results in a lowering of the circular member 32 but not of 3 l, and therefore conditions the translating device 3G for reproduction.

The member E9 may be rocked about the sleeve 43, to control the condition of the translating device, by a corresponding rocking of the rod 23 within the sleeve. To render this rod rockable, it may be freely fitted into the end standards 5 and 5 which support it, and its longitudinal retention therein may be by a substantially vertical screw 5b in the lefthand standard 5 extending into an annular groove 23h provided in rod 23 close to its lefthand extremity, as best seen in Figure 2. To couple the rod 23 to the member 65 for joint rocking, the rod may be provided with a longitudinal groove or keyway 23a, and a screw or key Gtia may extend from approximately the front of member Ell inwardly into the groove 23a, splining that member to that rod. There must of course be a passage of the screw 68a through the sleeve 43; the latter is therefore provided with a fractional-annular slot 43o: through which this passage may occur. 'Ihis slot is of length appropriate to the range of rocking of member 56 required for the several conditions of the translating device, and its extremities may form stops for preventing excess rocking of that member.

A manual control of the condition of the translating device may be provided by a lever 39 extending generally forwardly from a collar 83 which surrounds the rod 23 just to the right of the righthand carriage side member 42, and which is splined to the rod 23 by a screw or key 88a extending inwardly into the groove 23a.. When the lever 39 is in the position illustrated in Figure the translating device may be in neutral condition; and it will be understood that downward and upward rockings of the lever from this position will serve, by correspondingly rocking the rod 23 and therethrough the member 5E, to place the translating device in recordation and reproduction conditions, respectively.

It is desirable that the feed nut 21 be disengaged from the feed screw 25 throughout a neutral condition, but engaged therewith during either translational condition (i. e., for recordation or for reproduction), of the translating device. Accordingly the feed nut may be mounted, above the feed screw, on the bottom of a horizontal rearward exten-sion 68 formed from the top of the plate 49 abovementioned; and the plate 45 in its lefthand portion may be extended downwardly, to have an arm 65 folded forwardly therefrom and passing underneath the central roller 56. The arm 55 is biased upwardly, to force its top surface against that roller, by a suitable bias of the plate 4S about the rod 44; this bias may be provided by a spring 65 tensioned between cross rod 55 and a bracket 49 extending upwardly from the plate 49. The portion of the top surface of the arm 55 which bears on :the roller 55 when the translating device is in neutral condition is illustrated as 65, and when this bears against the roller the feed nut 2'! is held raised from the feed screw 25;

From this portion there slope downwardly the rearward and forward top surface portions 65a and 65h; and as the member 60 is rocked to move the rollers either rearwardly or forwardly (for adjustment of the translating device into either recordation or reproduction condition) the roller 56 travels over the surface portion 65a or 85h, the arm 65 moves upwardly in response to its bias, and the fed nut 21 is rocked downwardly into contact with the feed screw 25.

From the foregoing it will be understood that the carriage and translating device are freely movable manually relative to the record when the translating device is adjusted to neutral condition, but are movable only by the rotation of the feed screw when the translating device is adjusted for either recordation or reproduction. In the use of such a phonograph as has now been generally described, a conditioning of the translating device for reproduction will ordinarily be resorted to for the purpose of listening back by the dictator or operator to matter previously recorded on the record. At some point in the recordation process the control lever 39 will be thrown from its recordation into its neutral position, and the carriage and translating device will be "backspaced or returned some distance leftwardly, over `the portion of the record already recorded on. Then the control lever 35i will be thrown into its reproduction position and the carriage will again be driven slowly right-i wardly, with the reproducing stylus in contact with the record, to cause the reproduction of the recorded matter. There may or may not be desired a continuance of this reproduction to the end of that recorded matter before the reconditioning of the translating device for further recordation. When that continuance is desired, the point at which the audible reproduction stops furnishes an indication of where the translating device may properly be restored to recordation condition; this indication is not a positive one, however, and may result in some wastage of record space. And even this impositive indication is entirely lost when the abovementioned continuance of reproduction is not desired; at the end of the desired reproduction the control lever 39 must be thrown into neutral position and the carriage and translating device advanced by a distance which can only be estif mated, before throwing the control lever into recordation position. If the carriage is advanced too far before the reconditioning for recordation, wastage of record space results. If it is advanced .too little, the recording stylus will be brought down on and will obliterate previously recorded matter. Danger of bringing the recording stylus down on and obliterating previously recorded matter al-so lurks in the possibility of accidental throwing of the control lever into recordation position, instead of reproduction position, after returning the carriage leftwardly in preparation for the intended reproduction of recorded matter.

There are broadly known arrangements for preventing misoperations of this character. These arrangements involve so-called farthestadvance devices, moved by or in accordance with the advancing movement of the carriage, and a typical one of them has been disclosed in my co-pending application Serial No. 239,055; led November 5, 1938 (on which Patent No. 2,212,672 has since been issued). Such devices operate by making a temporary registration of the position of farthest advance attained by the translating device or carriage prior to a backspacing thereof; this registration is embodied in the position or condition of the farthest-advance device, and is maintained only until the translating device is brought into a new position of farthest advance. The instant invention, however, is designed to prevent these and other misoperations without employing such movable farthest-advance devices. In a broad aspect the instant invention operates by making permanent registrations of the positions at which the translating device is taken out of recordation condition, and by blocking any restoration of the translating device into recordation condition ex- Cepting at a position predeterminedly related tc the last-made such permanent registration. In another aspect, it operates by making registrations of the positions at which the translating device is put irnto and taken out of recordation condition, and by controlling subsequent placements of the translating device into recordation condition in accordance with both such registrations. In still another aspect, it operates by making a registration of any postion at which the translating device is taken out of recordation condition, by blocking the restoration of the translating device into recordation condition excepting at a position predeterminedly related .to such a registration, and by annulling the effect of each such registration (although that registration may be retained) as an incident of the next subsequent placement of the translating device into recordation condition. Such annulment may for example be effected in a manner which includes the making of another type of registration of each position at which the translating device is put into recordation condition. As will be apparent from the detailed description of an embodiment of the invention, its new mode 0f operation has various advantages, among which are of course the elimination of the many problems occasioned by the use of any form of movable farthest-advance device.

The broader aspects of my invention are not limited as to the precise place in which the registrations are made, but rather contemplate simply that the registra-tions for any record be peculiar, or individual, to that record. In the preferred embodiment of the invention, however, I have chosen to make the registrations on the individual index blank which it is common, in phoncgraphs of the general type described, to employ with each individual record. This blank typically is in the form of a paper or other slip, may be inserted in an appropriate holder in the phonograph when a record is mounted on the mandrel, and may be removed from the holder when that record is removed from the mandrel. An indicating means is commonly associated with the holder, to move longitudinally of the index blank in accordance with the movement of the translating device relative to the record. The broad function of the indicating means in cooperation with the blank may of course include the furnishing not only of a moment-to-moment indication of the translating device position relative to the record, but also of a guide or means for marking or annotating of the index blank to indicate points of error and/or correction in the recordation, lengths of dictation sequences, and the like.

In the illustrated phonograph a holder for an index slip has been shown as 30, disposed above the path of the carriage, for example in a vertical plane passing slightly behind the mandrel I0.

'Ihe holder may consist of a at plate, terminally secured to the standard and (through foldedback lugs 86h) to the standard S, and having retaining ange members 'i9 welded to its front surface near the top and bottom edges. These retaining flange members may if desired be integral with a vertical lefthand stop member i8, it being understood that an index slip S will be inserted leftwardly into the holder between the retaining ange members i9 until its lefthand extremity impinges against the stop member '13. To positively hold the slip S in this position until its removal is deliberately desired, there may be employed a catch member 'El biased to extend diagonally forwardly and leftwardly through an aperture Sila. provided in the holder just to the right of the righthand extremity oi a fully inserted slip. This catch member will be automatically cammed rearwardly by the slip during the slip insertion; will fly forwardly, upon the completion of that insertion, to the illustrated position wherein it blocks rightward movement of the slip; and may be pressed rearwardly, to permit deliberate rightward slip removal, by the ringer of the operator in the act of grasping the slip for removal. The catch member may have rearwardly extending top and bottom flanges lla, these being extended rightwardly behind the holder 8d to be pivoted on a vertical pin 'iii held between lugs Ilia extending rearwardly from the holder; and a torsion spring 'i5 encircling the pin 'it may be arranged to provide the bias for the catch member.

Figure 3 illustrates a typical index slip S, removed from the phonograph, while Figure 2 illustrates in dash-dot lines the periphery of the slip when fully inserted in the holder. Ey way of illustration, the upper portion of the slip has been shown as adapted to receive such marks or annotations as were mentioned above; and as a guide or means for making the latter, a pointer I4 will be seen extending upwardly from the carriage in front of the upper portion of the inserted slip.

In the illustrated structure the registrations which have been generally discussed above are made in the lower portion of the index slip. While it will be obvious that registrations of any of a variety of natures may be employed in carrying out my invention, and while I intend no unnecessary limitation in this respect, the preferred and illustrated embodiment of the invention employs registrations in the form of holes punched in the slip. These may for example be punched from the rear by a mechanism carried by the carriage and hereinafter detailedly described. To permit the operation of such punching mechanism on the slip, the holder 89 may be provided with a continuous longitudinal slot or aperture 8|, for example just below the horizontal center line of the holder, as best seen in Figure 2. As will hereinafter be apparent, the registrations made by punching through the slot 8l are registrations of the positions at which the translating device is taken out of recordation condition. Other registrations are made of the positions at which the translating device is placed into recordation condition; these may be made by punching through a slot or aperture 82 in the holder 89, below and parallel with the slot 8|. The two types of registrations, which respectively may be termed out and in registrations, are thus made in respective upper and lower paths on the index slip. Registrations of the two types appear as the holes Re and Ri, respectively, in the typical index slip illustrated in Figure 3.

The punching mechanism may best be seen in Figures 8 through 1l. This mechanism, and -a mechanism responsive to or actuated by the registrations and hereinafter detailedly described, are assembled to the carriage, being los cated to the right and left of the righthand and lefthand carriage side members 42 and 4| and above the carriage top member 46c. They are disposed within an inverted U-shaped housing whose righthand and lefthand side members are designated as S2 and 9|, respectively. Side member Q2 is held in spaced relation to carriage side member 42 through front and rear spacing posts 94 and i, respectively, while side member 9| is held in spaced relation to carriage side member 4| through front and rear spacing posts 93 and 95, respectively. The lower portions of the housing side members 92 and 9| extend forwardly and are terminally bifurcated. the extremity of 92 slidably iitting about rod 23, and the extremity of 9| iitting about the leftwardly extending portion of sleeve 43. The collar 88, from which the control lever 39 extends as above described, is retained about the rod 23 between the carriage and housing side members i2 and 92. And it is convenient to note at this point that between the carriage and housing side members 4| and 9| there is retained, in rotatably surrounding relation to sleeve 43, a generally similar collar 8l. Like collar 83, it is splined to rod 23; t'his splining may be by screw or key 87a extending inwardly to engage the groove 23a, in the rod, through an elongated arcuate slot 4322 in sleeve 43.

The punches for the out and in registrations appear as |0| and |62, respectively; each may for example be formed of flat material, may be disposed in a iront-and-back extending vertical plane, and may have a bifurcated front extremity to provide a double (top and bottom) cutting edge. In respect of side-to-side location, the punches may be disposed at approximately the center of the carriage, for example in alignment with each other. In respect of elevation, the punches are respectively disposed opposite the slots 8| and 82, the punch ||l| therefore being above I. The punches extend forwardly from and are carried by two respective bails |03 and |94, which extend from side to side Within the housing 90. The lefthand end members |05 and |06 of the two respective bails are curved rearwardly and then downwardly; and they extend, in closely spaced relation to each other, between the housing and carriage side members 9| and 4| down to a horizontal stud |69 secured in 4|, on which stud they are terminally pivoted (slightly spaced from each other and from 4| by washers such as lUSa). The righthand end members |01 and |98 of the two respective bails are similarly curved rearwardly and downwardly; and they extend, in closely spaced relation to each other, between the carriage and housingside members 42 and 92 down to a horizontal stud ll secured in 42, on which stud they are terminally pivoted (slightly spaced from each other and from 42 by washers such as Illia). Normally the bail end members will extend upwardly from the studs |59 and ||0 with a slight rearward inclination, resting against rearward stops which are conveniently provided by the spacing posts 95 and 9S abovementioned. They may be biased to this position not merely by gravity, but also by respective springs 2 and H3 tensioned from a cross rod 99 (extending between the housing side members) to respective pins ||4 and 5 extending inwardly from |06 and |87, respectively. When the bail end members are in this normal position, the forward punch extremities are spaced rearwardly away from the holder slots 8| and 82.

Each of the bails |D3 and |05 is moved iorwardly, to operate its respective punch through the respective slot 8| or 82, in response to a respective movement of the control lever 39, and thus in response to a particular re-conditioning of the translating device. More speciiically, the bail |93 may be so moved, to operate the punch IGI for making of an out registration, by the movement of the control lever from its recordation to its neutral position; and the bail |04 may be so moved, to operate the punch |02 for making of an in registration, by the movement of the control lever from its neutral to its rec ordation position. Conveniently, the mechanism for moving the bail |03 may be associated with the collar 8T (from which the lever 39 extends), and that for moving the bail |04 with the collar 88 (which, by virtue of the splinings abovef mentioned, moves co-ordinately with the co1- lar 81).

Referring first to the mechanism (illustrated principally in Figure 9) for moving bail |04, it

will be seen that approximately the lower half of the periphery of collar 88 is of reduced radius, excepting for a triangular cam 86 extending outwardly to the full collar radius in position to be directed downwardly slightly before the control lever 39 completes a movement from its neutral to its recordation position. The lower extremity of the bail end member |68 is extended forwardly from the stud lli); and at |0866, underneath the rod 23, there is pivotally secured against the lefthand face of |03 a pawl ||8 having a pointed A extremity ||8a normally extending upwardly almost into contact with the reduced-radius periphery of collar 88. A lug ||8b folded rightwardly from the lower portion of the pawl normally abuts against a shoulder |6817` formed by downwardly widening the member |68 forward of the point |3805; this abutment is normally maintained by a spring |2! tensioned between lug H813 and a lug |080 folded rightwardly from the front extremity of |68.

As the control lever 39 is rocked downwardly from its neutral (Figure 9) position into its recordation position, the cam 86 will presently engage the pointed extremity lilla. of pawl ||8. The abovementioned abutment of lug against shoulder prevents that pawl rotation which would move its extremity ||8a rearwardly, so that the pawl remains stationary relative to member |83; consequently as the lever rocking is continued the pawl will be forced downwardly by the cam, moving the bail end member |08 counterclockwise (as seen in Figure 9) about stud HU, and thus rocking the bail |64 forwardly to project the punch |62 through the slot 82 for punching of an in registration in the slip S in the holder 3E). As the lever rocking is completed the pawl extremity ||8a will be just fully disengaged by the cam 86, so that the bail and punch will have returned to their normal positions under the influence of their bias. It will of course be understood that upon the reverse movement of the control lever 39-i, e., from recordaticn into neutral positionthe engagement of the pawl extremity ||6a by the cam 86 will be ineffective on the bail |04 and punch |32; the pawl will simply yield with counterclockwise rotation (as seen in Figure 9) about the pivot point ia, to pass the cam without movement of |88.

Referring now to the mechanism (illustrated principally in Figure 10) for moving bail |03, it will be seen that approximately the lower half of the periphery of the collar 8l is of reduced radius, excepting for a triangular cam 85 extending outwardly to the full collar radius in position to be directed downwardly slightly before the control lever 39 (which influences this collar through the splinings abovementioned) completes a movement from its recordation to its neutral position. The lower extremity of the bail end member |85 is extended forwardly from the stud m9; and at la, underneath rod 23, there is pivotally secured against the righthand face of |55 a pawl having a pointed extremity Il'la normally extending upwardly almost into contact with the reduced-radius periphery of collar 8l. A lug ||1b folded leftwardly from the bottom rear portion of the pawl normally abuts against the bottom of the member It; this abutment is normally maintained by a spring ||9 tensioned between lug |I'Ib and a lug H3513 folded leftwardly from a more rearward portion of |65.

As the control lever 39 is rocked upwardly into its neutral (Figure 9) position from its more downward recordation position (rocking collar 8l into its Figure l0 position from a more counterclockwise one), the cam 85 will presently engage the pointed extremity H'ia of pawl The abovementioned abutment oi the lub ||'|'b prevents that pawl rotation which would move its extremity Illia forwardly, so that the pawl remains stationary relative to member |85; consequently as the lever rocking is continued the pawl will be forced downwardly by the cam, moving the bail end member |65 counterclockwise (as seen in Figure 10) about the stud H39, and thus rocking the bail |33 forwardly to project the punch iii through the slot 8| for punching of an out registration in the slip S held in the holder As the lever rocking is completed the pawl extremity Illa will be just lully disengaged by the cam S5, so that the bail and punch will have returned to their normal positions under the influence of their bias. It will of course be understood that upon the reverse movement of the control lever SS-i. e., from neutral into recordation positionthe engagement of the pawl extremity lila by the cam 85 will be ineffective on the bail |93 and punch Ii; the pawl will simply yield with clockwise rotation (as seen in Figure l0) about the pivot point Ilia, to pass the cam without movement of |95.

From the foregoing there will be understood one exemplary and preferred manner in which I may make registrations of the positions at which the translating device is placed into and taken out ci" recordation condition. In accordance with my invention, I control the subsequent conditioning of the translating device-or, more specifically, the subsequent manipulation of the control lever Bilin accordance with the precedingly made registrations. More specific aspects of this control are hereinafter developed. At this point, however, I may note that in effecting this control I make use of a mechanism responsive to the precedingly made registrations, and such mechanism may now conveniently be described. It may comprise a pair of scanning devices, respectively actuated by the in and out registrations.

Each scanning devicem'ay be actuated Vby a registration of its respective type when the translating device occupies a position predetermnedly related to the position occupied by the translatingi device when that registration was made. By way of prei erred example, the scanning device responsive to each in registration may be actuated when the translating device occupies a position of substantial identity with the position it occupied when that registration was made, while the scanning device responsive to each out registration may be actuated when the translating device occupies a position slightly advanced from the position it occupied when that registration was made. In the embodiment of the invention illustrated in the figures through Figure 15 the scanning devices comprise two electric switches, respectively associated with the slots and B2, the actuations of the devices comprising closures of the switches.

The switch actuated by the out registrations is designated in its entirety as |2|. As seen in Figures 8 and 9, it is positioned within and near the top of the housing gli, its rear extremity being pivotally assembled onto a cross rod 97 extending between the sides of the housing above the cross rod Si) abovementioned. While some of the details of the switch |2| appear in Figures 8 and 9, they are better illustrated in the enlarged Figures 3.2 through l5. The switch may comprise an inner, generally channel-shaped casing |23, and an outer, inverted channel-shaped casing Ille; these casings are preferably of insulating material. The sides of the outer casing |25 are extended rearwardly to form lugs |2541 through which the cross rod 97 pivotally passes, and are extended forwardly to form lugs |2517 between which is supported a cross pin |27. The base of the inner casing |23 is extended rearwardly to form the bifurcated hub Hita pivotally surrounding the cross rod ST between the lugs |25a, and is upwardly thickened in its bifurcated forward portion EES-h. The cross pin |21 passes through this portion |231), rendering the inner and outer cassecure with respect to each other-their eeparability being simply for purposes of assembly. To the base of the inner casing, near its rear, there is secured an insulating stack |29; and normally open contact springs |3|a and |3513 are held in and extend forwardly from this stack. Each side of the forward portion |231) of the inner casing is provided with a respective narrow vertical slot iilc. Through these slots, and pivoted on the cross pin |2lr where it passes transversely through the slots, there extend into the interior space between the casings two respective levers |33. At the rear extremities of these levers there is secured between them a horizontal cross pin i3d, up against which the top contact spring |3 io may be lightly biased. It will be understood that the function of the pair of levers |33 is at appropriate times to press the cross pin 35 downwardly against the spring 3| a, thereby moving the latter into contact with the contact spring |315 and so closing the switch I2 I-connections to the switch being made by conductors |31 passing inwardly of the casings at the rear of 23 and respectively connected to the contact springs |3|a and l3lb.

Outside and at the front of the casings the levers |33 extend a short distance downwardly and slightly forwardly, and are then joined together by a bridging member |33a disposed in a vertical plane; in the intermediate portion of the bridging member |33a it is formed into a V-shaped nose it?) having a forwardly directed apex. A torsion spring |39 is wound about the cross pin i'l'betweenthe sides of the casing portion |23h, and is terminally secured to that casing portion and to the nose ESSI); it serves to bias the nose |33b forwardly and the levers thus into switchclosing position. The entire switch |2|, its rear pivoted on cross rod ill' as abovernentioned, is held in a normal substantially horizontal position by a large pin mia extending leftwardly, from an upward projection litio on the bai-l end member it?, some distance forwardly of the cross rod oli-this pin lilla extending to underneath a rightward extension .125e of the outer casing ilii. In this way the switch is supported so that the nose lih is normally at the mean level of the punch itl (and thus of the registrations R0 made by that punch in the slip S). And, as ful'- ther illustrated in Figure 9, the front-and-back disposition of the switch is such that the nose |331) will extend into the slot til-and such that the nose will normally be held, by the rear surface of the slip S in the holder Bil, suiliciently rearwardly against its bias to maintain the switch |2| open. (The nose will of course be displaced forwardly by its bias and the switch thus closed when no slip is in the holder, but the slip during its insertion will cam the nose rearwardly into the illustrated and described position.)

It ni ay here be noted that the entire switch |2| (as well as the entire switch l2?, below described) is held in a xed, substantially central side-toside position within the housing .t8 by washers 953e secured on the cross rod 99 and extending therefrom suidciently to be abutted against by the rearwardly extending lugs iZa (and by the analogous elements in the switch |22).

From the above description it will be obvious that the bridging member |33@ from which the nose |331) is formed lies in the path which the punch 9| must traverse when it is projected forwardly through the slot di to make a registration in the slip S. To remove the bridging member from that path when the punch ||3| is operated, the entire switch ll may be automatically rocked upwardly about cross rod 97; this is arranged for by beveliing the bottom of the casing extension |250 diagonally downwardly for a distance forwardly from the normal position of contact with the pin lilla, so that when the bail |03 is rocked forwardly to project the punch through slot 3l, the entire switch |2| is cammed upwardly. In turn, the slot 8| is made with a sufficient dimension above the normal level of the punch il and nose llb to permit the temporary raising movement of the latter within the slot. To insure the prompt return of the switch |2| to its normal position upon the return of the bail |03 to its normal position after a punching operation, a torsion biasing spring |l| may be wound about the cross rod itl' and its terminals respectively engaged with the switch |2'l and with a stationary member' such as cross rod $9.

The switch actuated by the in registrations is designated in its entirety as i22. As seen in Figures 8 and 9, it is positioned within the housing et, below the switch VE l its rear extremity being pivotally assembled onto a cross rod S3 ex- Lenclmg between the sides of the housing below the cross rod t9 abovementioned. Subject to such few exceptions as may hereinafter appear, the switch |22 may be an inverted duplicate of the switch i2 I detailed description will therefore not be repeated, but it will simply be noted 'that parts of and immediately associated with the switch E22 have been assigned reference numerals each higher by l than those assigned above and in the drawings to the corresponding parts of and associated with the switch |2|. It will of course be understood that upanddown and right-andleft (but not the front-and-back) relationships of parts will be reversed in the switch |22, in view of its inversion; thus for example the external portions of its levers |34 will extend, from the front of the casings, generally upwardly rather than downwardly, but the biasing of the nose I'llb (by spring |48) will, like that of the nose be a forward, switch-closing bias.

The entire switch i2?. is held in a normal substantially horizontal position by a large pin IOEa extending rightwardly from the bail end member |56 some distance forwardly of the cross rod 98. This pin extends into association with a leftward extension IEGc ef the outer casing |25 of the switch; but instead of extending underneath that extension, the pin ia extends into a slot |26c' cut into the lelthand face of the extension |266, and passing from the top surface of that extension diagonally rearwardly and downwardly to near its bottom surface. The entire switch |22 is strongly biased upwardly about the cross rod S8 by a torsion spring |42 wound about that cross rod and having its terminals respectively engaged with the switch and with the cross rod 99; this causes the bottom-rear extremity of the slot |260 to bear upwardly against the pin lc therein, establishing the normal position of the switch. This position is such that the nose |341) is normally at the mean level of the punch H32 (and thus of the registrations Ri made by that punch in the slip S) the nose will extend into the slot 82 and will normally be held, by the rear surface of the slip S, sufficiently rearwardly against its bias to maintain the switch |22 open.

The bridging member |34@ from which the nose |342) is formed of course lies in the path which the punch |92 must traverso when it is projected forwardly through the slot 32 to make a registration in the slip S. To remove the bridging member from that path when the punch |62 is operated, the entire switch |22 is automatically rocked downwardly about the cross rod 9B; this is ac complished by the diagonal arrangement of the slot i2fc already described, which causes the pin |06a to cam the entire switch downwardly, against its bias, when the bail ll is rocked forwardly to operate the punch |82. In turn, the slot 22 is made with a sufficient dimension below the normal level of the punch |92 and nose |3419 to permit the temporary lowering movement of the latter within the slot.

It may be noted that, for reasons hereinafter apparent, the side-to-side position of the nose |3323 is preferably displaced very slightly leftwardly (i. e., in a direction opposite to that of carriage driving) from the associated punch Il, while the nose llib is preferably in side-to-side alignment with its associated punch 62. This is illustrated in Figure i5, showing the two noses, when considered in connection with Figure 11, showing the two punches.

From the construction as above described it will be understood that during the rightward travel of the carriage the noses |3313 and |34b constantly press against the rear of the index slip S. When the nose |3312 reaches a registration R already made in the slip-which it will preferably do when the translating device is Very lightly advanced beyond the position it occupied when that registration was made-that nose moves forwardly into that registration, the distance of this movement being sumcient to actuate, or cause the closing of, the switch |2|. And when the nose |341)` reaches a registration R1 already made in the slip-which it will preferably do when the translating device occupies the same position as when that registration was madethat nose moves forwardly into that registration, actuating or closing' the switch |22.

The description of the illustrated mechanisms for making and for responding to the registrations may be completed by noting the preferable use of an anvil member |45 immediately in front of the index slip-this member moving with the carriage, and acting as a die for each of the punches I0 B2 and as a reinforcement for the slip against the constant forward pressure of the noses |33b-I34b. The anvil member proper is best seen in Figures 6 and 7. It may comprise a block |46 extending upwardly from the carriage top member 40o, its rear vertical edges being bevelled to present a relatively narrow vertical surface to the front of the slip S in the holder (as may also be seen in Figure 1). The upper lefthand half |4611 of the block |46 is made removable; and in it from front to back, before its assembly to. the rest of the block, are cut two slots |41 and |48, each of cross-sectional dimensions corresponding to those of the ends of the punches, and having their rear extremities aligned so as to be entered by the respective punches upon operation of the latter. The slots may lead diagonally downwardly and forwardly, to facilitate the forward expulsion therefrom of punchings from the index slip. To trap and accumulate these punchings there may be removably attached to the front of the block |46 a cover member |50. This may have a top portion la, extending rearwardly over the front portion of the top of the block |46, and having a narrow edge |5011 folded downwardly along its rear extremity to t removably in a side-to-side slot |4613 cut in the top of the block |46; and it may have side portions |560, extending rearwardly over the front portions of the sides of the block |45, and slotted in their bottom edges to be removably engaged by screws |49 respectively extending into the bottom portions of the block sides.

The pointer T4, above referred to, may be secured to and extend upwardly from the top of the block |46, to move in front of the upper portion of the slip S held in the holder 80.

One non-limitative way in which I have contemplated employing previously made registrations to control the subsequent conditioning of the translating device is the blocking of the placement of the translating device into recordation condition excepting at a position predetermined by those registrations. In doing this I may employ a means which normally blocks that conditioning of the translating device, but which is rendered ineffective by the means responsive to or actuated by the registrations-e g., by the switches lill--I-under certain conditions. Such a blocking means has been illustrated in Figures 1, 2 and 5, and may now be described.

The front carriage rod, just to the right of the lefthand standard 5, is provided with a recess |53. The rod being taken as in the position it assumes when the translating device is in neutral condition, (as illustrated), this recess may be described as formed by a vertical radial cut extending from the top of the rod downwardly for about a quarter of the rod diameter, and by a horizontal cut extending forwardly from the ywas previously taken out of that condition.

bottom of the vertical cut to the rod periphery. In the drawings the vertical surface of the recess is indicated as |53a, and the horizontal surface as |53b. A latch member |54 is pivoted to a stationary member disposed to the rear of the rod 23 (as hereinafter more specifically noted), and extends forwardly to have the latch I 54a folded downwardly at its front extremity; when the translating device is in neutral condition, the latch |54a will normally rest in the recess |53, closely adjacent the vertical surface |53a. It will be understood that this latch, so long as it occupies the stated position, will by engaging the surface |53a prevent that rotation of the rod 23 which accompanies a placement of the translating device into recordation condition, and hence will prevent such a conditioning of the translating device. It does not, however, prevent the free re-conditioning of the device between neutral and reproducing conditions, since the generally horizontal surface |531) will then act effectively as a cam for the latch.

For removing the latch from the stated position under certain circumstances there may be employed an electromagnet |56. This has been illustrated as comprising an inverted U-shaped frame |58 held as bybrackets |51 against the righthand surface of the standard a vertical core |59 extending centrally within the frame; and a coil |60 surrounding the core within the frame. The latch member |56 may be pivoted to the lower rear extremity of the frame |58; and when in its above-stated position it may be slightly spaced below the bottom end of the core |59-being biased downwardly, if desired, not

only by gravity but also by a light leaf spring |6| secured to the front of the frame |58. It will be understood that upon energization of the electromagnet the latch member |53 will be attracted upwardly into contact with the end of the core |59, raising the latch |5311l above the top of the rod 23-and so rendering ineffective, or releasing, the blocking means above described.

The electromagnet |56 is energized, and the blocking means thus rendered ineffective, under the control of the switches |2| and |22; an electrical circuit suitable for effecting this control is shown in Figure 4. The basic circuit, shown in heavy lines, may comprise simply a series connection, across the current source as typified by the plug |63, of the electromagnet coil |60 and the switch |2| and a current-limiting resistance |64. The circuit as thus described is arranged to energize the electromagnet whenever the switch |2| is closed-i. e., to release or render ineffective the blocking means whenever the nose |331) reaches a previously made out registration Ro, or, in still other words, to permit the placement of the translating device into recordation condition when it occupies a position very slightly advanced from a position at which it (It will of course be understood that the reason for the slight side-to-side displacementA of the nose v|33b and punch |ii| relative to each other, as

above described, is to enforce the slight advance just mentionedthe latter being desirable for well understood reasons, including the provision of a positive assurance that the recording stylus will not be brought down on the terminal portion of a recording already made on the record.)

Of course if it were possible to assume that with any given record the translating device would be taken out of and returned to recordation condition no more than once, the arrangements and their functions as so far described would be suiiicient to insure that its return would be effected at the proper position. Such an assumption obviously cannot be made, however, since there is no limitation on the number of times that the translating device may be so manipulated, for listening-back or other purposes. I therefore keep the blocking means effective not only when switch |2| is open, but also whenever it is closed by the nose |33h encountering any one of the out registrations Ru excepting the last-made one of those registrations. To do this is a principal function of the in registrations Ra and the switch |22 responsive thereto. Structurally these have already been describedand it is here recalled that a respective registration Ri is made for any position where the translating device is placedrinto recordation condition, and that the switch |22 is closed so long as the translating device remains in, and whenever it is returned to, that position.

In considering the action of the registrations Ri and the switch |22, let it rst be assumed that the translating device is traversing a given record without yet having been taken out of recordation condition. When it is taken out for the first time, a registration Ro is made, such as that specially designated as Ro in Figure 3. The translating device vmay be backspaced and placed in reproduction condition (for listening-back purposes), or otherwise manipulated, but it can be restored to recordation condition only at the one position which causes the nose |3311 to come into the registration Ro. When it is so restored at this one position, the adjacent registration Ri" is made; and not only so long as the translating device may remain in this one position, but also whenever it is returned thereto, both switches |2| and |22 will be closed. As indicated in Figure 4, switch |22 may be connected across the electromagnet coil |60; therefore its closure, by short-circuiting the electromagnet, annuls the electromagnet-energizing effect of the closure of switch |2| (it being noted that the resistance |64 prevents a short-circuiting ofthe current supply). Thus the effect of the registration R0, to permit the restoration of the translating device into recordation condition at a position slightly advanced from that which it occupied when that registration was made, is annulled by the registration Ri" automatically made upon that restoration. If, either before cr Vafter further record traversal in recordation condition, the translating device be again taken out of that condition, another out registration such as Ru" Will be made. .Althoughthe previous registration Ru" physically remains besides the new registration, its effect has just been seen to have been anulled by R1, and thus the last-made out registration Ro'" is the only one now effective to establish a position at which the translating device may be restored to recordation condition. 'I'he registration Ro", too, would be anulled effectively when the translating device was again placed into recordation condition, so that a still subsequently made out registration would become the only effective one-and so on, so that only the lastmade ,out registration is effective in establishing that single position at which the translating device may be restored to recordation condition.

In the preceding paragraph it was initially assumed that the translating device was traversing a record in recordation condition. With the system as above described, however, someprovision must be made to permit the placement of the translating device into recordation condition in the rst instance-i. e., for the beginning of the traversal of the record. This may be accomplished by providing for all records uniform initial registrations, each simulating an out registration actually made in the phonograph but positioned to actuate the device responsive to out registrations (e. g., the switch |2|) when the translating device is at the very initial position in its range of traversal of the record. When the registrations are made in the index slips S, such initial registrations may be incorporated in the slips when manufactured; and when the registrations are in the described and illustrated form of holes punched in the slip, the initial registration may be a like hole such as R0 in Figure 3. Upon the initial placement of the translating device into recordation condition (now effectable only at its proper initial position) there will of course be made' a registration R1' adjacent to, and of annulling effect upon, the initial registration Ro.

It may be noted that if those who prepare the records for use wish for any reason (such as a defective condition of the initial end portion of a particular record) to restrict the area of a record to be recorded on, they may supply that record with a special initial registration-e. g., a specially placed initial Rn registration in the accompanying slip-either without the usually placed initial Ro registration, or with the latter annulled by an appropriately placed Rl registration. Thus my invention provides a way of establishing a definite position, which may be peculiar to any individual record, at which recordation on that record may be initially begun.

It may also be noted that the operator of the machine, when desiring to place the translating device from neutral into recordation condition (whether or not the record has been partially recorded on already will slide the carriage along its rods, either with a continued downward pressure on the lever 39, or without such pressurein the latter case until he hears the signal inherently provided by the operation of the electromagnet |55, apprizing him that he has reached the one position at which he may effectively exert downward pressure on the lever.

It will be understood that while I have so described in detail a particular and preferred embodiment of my invention, many of its individual features are-subject to wide modifications With- .out departure from the spirit or true scope of the invention. By way of example, the non-limitation to the index blank as a necessary member for receiving the registrations, the non-necessity for punching as a particular means of eifecting the registrations, and the like, have already been mentioned. By way of further example, the invention is not limited to the use of electrical scanning devices responsive to or actuated by the registrations. Thus in Figures 16, 1'1 and 18 I show modifications of a portion of the phonograph of earlier gures, which modifications involve the substitution of mechanical scanning devices responsive to the registrations. It will be understood that in these gures only so much of the phonograph and its parts has been illustrated as is necessary to show the alterations; and to simplify the showings of the portions actually illustrated, there have been omitted therefrom the punching means and the like, the use of which as a typical registration-making means is contem- "plated as before.

gestiva In Figures 16 through 18 the scanning devices actuated by out and in registrations are generally designated as 22| and, 222, respectively. The principal portions of these devices, like |2| and |22 above described, may be respectively pivoted on the cross rods 91 and 98. The device 22| `may comprise a casing 225 generally similar to the outer casing |25 of earlier figures, though preferably having Athicker sides and front lugs 225D, against which latter fit the levers 233. These are generally similar to the levers |33 of earlier figures, again being supported on cross pin |21 and having bridging member |3311 with nose |331) and being biased by spring |39; but rearwardly the levers 233 may extend a little further, with a slight downward curve, to supp'ort the cross pin 231 between their rear extremities. The casing 225 may be biased downwardly by torsion spring 24 (analagous to |4| of earlier rigores), and may be supported-and cammed upwardly when the punch |9| is operated-by pin ||i1a as was the casing |25 of earlier figures.

The principal portion of the device 222 may be essentially an inverted duplicate of that just described, in the same way as |22 was an inverted duplicate of |2I, and the description immediately above may be applied thereto with the designating numerals each increased by 1. It will of course be understood that the casing 226 may be biased upwardly by torsion spring 242 (analagous to |42 of earlier figures), and may be positioned normally-and cammed downwardly when the punch |02 is operated-by pin |96a as was the casing |29` of earlier figures.

The scanning device 22| may be considered as further comprising an arm |1| which has a bifurcated forward extremity engaging the cross pin 231, and which has a central portion pivoted on the cross rod 99-the central arm portion preferably being secured to the righthand face of a sleeve |13 extending rightwardly from the lefthand washer `99a about cross rod 99. From the cross rod S9 the arm |1| extends rearwardly, and is terminally widened in an up-and-down direction.; its rear edge |1|b is shaped as an arc about the cross vrod 99, and in the lower portion of that edge there is cut inwardly a V-shaped notch `|1|c. When the nose |33b encounters a registration and moves forwardly in response to spring |39--i. e., when the scanning device 22| is actuated-the cross pin 231 is rocked a little ways downwardly, and thereby the rear edge |1|b of arm |1| is rocked upwardly to bring the notch A|1|c up Vto the level of the cross rod 99.

The scanning device 222 may correspondingly be considered as further comprising an arm |12 lwhich has a ybifurcated forward extremity engaging the cross pin 238, and which has a central portion `pivoted on the cross rod 99--the central arm portion preferably being secured to the lefthand face of a sleeve |14 extending leftwardly from the righthand washer 99a about cross rod 99. From the cross rod 99 the arm |12 extends rearwardly, and like arm |1| is terminally widened in an up-and-down direction; `also like the rear edge of arm |1|, its rear edge |121) is shaped as a similar-radius arc about the cross rod 99, but in this edge a V-shaped notch |12c is centrally cut, to be at the level of the cross rod 99 when the device 222 is unactuated. When the nose |342) encounters a registration and moves forwardly in response to spring |4D-i. e., when the scanning device 222 is actuated-the cross pin 238 is rocked 'a little ways upwardly. and

thereby the rear edge |1212 of arm |12 is rocked downwardly to carry the notch |120 below the level of cross rod 99 abovementioned.

A pin is supported and forwardly biased, in manner hereinafter described, behind the edges |1|b and |12b at approximately the level of the cross rod 99. At all times when either the scanning device 22| is unactuated, or the scanning device 222 is actuated, or both these conditions obtain, the pin |15 is held in a normal position as illustrated in Figure I17, wholly behind the arcuate contour of the edges |1|b and |121) (analogously to the electromagnet |58 remaining' unenergized when either the scanning device |2| was unactuated, or the scanning device |22 was actuated, or both those conditions obtained). But when, and only when, the scanning device 22| is actuated and the scanning device 222 is unactuated, both the notches |1|c and |120 are in alignment with each other at the level of pin |15, and that pin moves forwardly thereinto (analogously to the electromagnet |56 being energized when the scanning device |2| was actuated and the scanning |22 was unactuated).

There may now be described the manner in which the position of the pin |15 enforces and releases a blocking of the placement of the translating device into re-cordation condition. The pin |15 extends leftwardly, to behind the edges |1|b and |1213, from the free extremity of a lever |10. This lever leads from the pin downwardly and then forwardly to be pivoted on a cross rod |00 extending between the housing side members 9| and 92 below the cross rod 93; the cross rod H may be surrounded on the respective sides of the lever |15 by the sleeves |00a and web, to one of which the lever may be secured. From the upper edge of an intermediate portion of the lever |16 there is folded rightwardly a lug |11; and from the lower edge of that lever portion, below lug |11, there is folded rightwardly another lug |18. Against the righthand side of the righthand housing side member 92 there is pivotally held, on a stud |80 axially aligned with the `cross rod |00, a lever I8I. This lever |8| extends from stud |80 rearwardly to behind'the housing side member 92, and from its rear extremity there is folded rightwardly a lug |82. This lug |82 overhangs the lug |11, and these two lugs are biased into contact with each other by a spring |19 tensioned from lug |82 to lug |18.

The lever |'8| extends forwardly from the stud |80 to terminate diagonally below and behind the rod 23. Its forward portion may be made suiciently heavy, as by the local enlargement |8| a, to somewhat more than counteract the rotating force of its rearward portion about stud |80 plus the rotating force of lever |16 about cross rod |00, thereby electing the abovementioned forward bias of the pin |15-but not sufficiently heavy to cause the expansion of spring |19 with consequent separation of the lugs |82 and 11 from contact with each other.

About the rod 23 there is secured, in side-toside alignment with the lever |8|, a collar |84 having, generally at its rear, a reduced-radius portion separated near the bottom of the collar from the full-radius portion of the collar by the shoulder |84a. When the translating device is in neutral condition the forward extremity of the lever |8| extends into substantial abutment against this shoulder. The reduced-radius portion of the collar freely permits the shift of the translating device between neutral and reproduction conditions; but normally any placement of the translating device into recordation condition is blocked by the impingement of the shoulder against the lever extremity, which elements may thus be considered as the blocking means in this embodiment. But when the pin |15 is permitted to move forwardly into the notches |1|c and |12c as above described, the lower extremity of lever |8| moves downwardly to clear the shoulder |84a, then and only then rendering the blocking means ineffective. The analogy of this action to that of the preceding embodiment will be apparent without further description.

It may be noted that the function of the yieldable contact between lugs |82 and |11 is to permit the forward lever extremity to be held downwardly displaced Iby the full-radius portion of the collar |84, after recordation condition of the translating device is once established, even when the pin |15 is thereafter forced rearwardly to the illustrated position.

It will be understood that with either embodiment of my invention it `is impossible to place the translating device into recordation without a slip being inserted in the holder-since both the scanning devices will then be actuated and the blocking means therefore unreleased. As above noted, the slip in its insertion cams these noses rearwardly.

While I have described and illustrated my invention in terms of preferred embodiments thereof and for a preferred use, I intend thereby no unnecessary limitations. Obviously the translating device need not be one adapted for two alternate functions, but may simply be selectively conditionable in one predetermined translational condition and in one other condition (e. g. neutral) with respect to the record. And while the invention may have its greatest utility when that predetermined translational condition is recordation condition, no unexpressed limitation thereto is intended. Not only in these b-ut also in many other respects it is obvious that the disclosed embodiments are capable of wide changes without departure from the spirit or scope of the invention.
